1. A method for directing high-intensity beams toward a swarm of unmanned aerial vehicles (UAVs), the method comprising:
receiving a location of the swarm of UAVs;
determining one or more radio frequencies associated with the swarm of UAVs;
orienting, based on the location, a directional antenna toward the swarm of UAVs;
adjusting an aperture of the directional antenna;
receiving an authorization input;
emitting, via the directional antenna and based on confirmation of the authorization input, an RF signal, wherein:
the RF signal comprises RF energy at a power configured, along a beam axis of the directional antenna at a range between 1 kilometer and 1.5 kilometers from the directional antenna, to disable the swarm of UAVs; and
the RF energy decreases outside a field of view of the directional antenna; and
monitoring the one or more radio frequencies to determine whether the swarm of UAVs has been destroyed or disabled.
